Dell ThinOS 9.x 2502, 2505 and 2508 Migration Guide

Introduction

This guide provides instructions to migrate from Ubuntu and ThinOS 9.1.4234 or later versions to ThinOS 9.x 25xx using Wyse Management Suite 4.0 or later versions.

The migration process includes the following tasks:

Register the device with Wyse Management Suite by automating the discovery of the Wyse Management Suite server and Group Registration Token using DHCP or DNS records.
Download the ThinOS firmware from the Support | Dell site—see Download the ThinOS firmware, BIOS, and application packages.
Configure the ThinOS 9.x-based device using Wyse Management Suite version 4.0 or later versions—see Configuring a ThinOS 9.x client using Wyse Management Suite.

When converting a device from a different operating system to ThinOS 2303 or later, or when installing the ThinOS 2303 or later recovery image, ThinOS sets the following BIOS settings during the initial boot:

BIOS password: Fireport
SATA/NVMe Operation: AHCI/NVMe
Integrated network adapter: Set to Enabled (set to disable PXE boot support)
Wake-on-LAN: LAN only
NOTE:For OptiPlex 3000 Thin Client with SFP module, the option is set to LAN or SFP NIC.
Enable Secure Boot: ON
Enable USB Boot Support: OFF
Enable USB Wake Support: ON
Deep Sleep Control: Disabled

NOTE:These BIOS settings change only apply to devices with the BIOS password set to Fireport or with an empty password field.

NOTE:Third-party packages released before ThinOS 2205 will be uninstalled when you upgrade to a later ThinOS release.
